a citizen ofthe United States, and resident ofBrookline, in the county of` Norfolk and 5 `State of Massachusetts, have invented new mats, and other and useful? provements in Fabric for Mats`,`Rugs-, &c., *lof `which the following is a specification.

My linvention relates yto rugs, carpets, coverings, one object of my invention being to prevent such a covering placed upon 1agslippery surface, for instance a polished .-fl oor, without fastening means, from slidingv `under use. Other objects' of myl inventnrefto provide improved Pro" tection 'againstwear adaptable to the under surface of; woven carpets, rugs, mats and other fabrics adapted to use as lioor coverings 'e g Further objebts of my invention are to provide a structure for such rugs, carpets or other ..textiles applicable either during manufactur'eor to previously made articles, which Willpresent ,a frictional surface "capable'of maintaining a detached section of the down under tension,

accidents on the under surface of carpet or fother textile in 5 lie with relative freguency iny reason of the lack of 'friction between the under surface of the rug and a polished `floor. I yhave discoveredl that this diiculty may be permanently avoided t such ioor coverings the Hoor presenting friction with respect parts of points of contact with a higher coeflicient of tothe floor than the projecting I vthe modification lnvention;

`ble-faced pile fabrics,

ctural -warps 2, stuffer weft prising strong' s warps 3, and strong surface resting upon l V being made up of the wefts 4 bowed out by the stuifer warps 3 between their places of engagement by the warps 2. Carpets and rugs of this general structure, of which there are many variants well-known to those skilled in the art, therefore stand upon a number of separated feet, necessarily of a hard, slippe yarnt In al1 carpetsv and rugs with Whlch I am famlliar, except do1 1- the vunder surface 1s yarns 4, the under which existing'fabrics may the floor in use usually.

some'form of reticulation presenting higher ployed the back ofthe fabric structural warp 2, at

' desired, for

places which form the only frictional con` tact with the iioor.

In one form of my invention, as shown in Fig. 1, one of the structural yarns brought by the structure of the weave, whatever that may be, to the back surface at frequent intervals is so treated as to cause it to stick to the floor. Preferably I treat a yarn or yarns 5 with an adherent sticky substance forming a frictional coating on the yarn. Such a coating, which may if desired penetrate the body of the yarn, may be formed by immersion or by spraying or padding on any suitable gummy or sticky composition, such as a solution or compound of unvulcanized or partially vulcanized rubber in suitable solvent, or such a composition rendered fluid by heat; or I may employ any of the well-known compositions of matter having as an ingredient an oxidized oil; or a lcolloid substance such as bichromated glue, gum, gelatin, wax or the like; or a substance composed of a vegetable oil .brought to a viscous or solid state by suitable combined reagents and vulcanizing or viscolizing treatments. In general, any compound or mixture suitable for adhesive plasters or adhesive tapes havingv the characteristic of adhesion to hard, smooth surfaces, preferably without leaving particles on the surface when removed, may be em- As illustrated in Fig. 1, changed during every sixth pick for a treated weft 5 whereby, as illustrated at 6, the bowed out portions at the back of the fabric at every third reticulation are of the sticky covered yarn. While I have illustrated this numerical relation, it will be understood that the entire wef be treated, if desired, or that the separation of the treated wefts by untreated wefts may be greater than or less than illustrated, the treated weft for instance being thrown across the lopen 'shed at every twelfth or every twentieth pick. I have shown the weft returned on the' next pick, Fig. 1.

I may, as shown in Fig. 3, employ a oontinuous untreated weft 7 Aand throw the treated weft 5 .through the open shed along with the untreated weft at such intervals as v instance asillustrated,l at every sixth pick, returningthe treated and untreated weft together during the following pic l l' In some cases it is more convenient for manufacture to avoid weft changes, and in that case I may employ the expedientv ustrated in Fig. 4 inwhich one ofthe stufi'er warps is a coated yarnI 5, and. is shed out at along with the intervals of a plurality to project from the back face the weft 4 is exof picks, so as of `the fabric. l I I may secure mugh the same result, as

y properly illustrated in Fig. 6, by providing onev of the stuffer warps 3, as shown at 30, with a coating of the frctional material, and holding said warp with little tension so that successive beat-up slackens and projects it in loops, as illustrated at 31, which may be caused to lie on the back of the fabric by positioning the warp 30 with respect to the other stufer warps 3, as will be understood by weavers. In some cases I prefer to so weave the base fabric carrying any suitable pile formation as to cause the warps to rest on the floor, and as illustrated at Fig. 5, in this case an occasional warp 12 may be treated with the described frictional coating.

When making the structure of Fig. 4 of Fig. 5 or. Fig. 6, for economy of the sticky addition to the yarn or for ease in handling and for other purposes, I may employl a, treated yarn as illustrated in Fig. 7 havin a coating 50 applied at intervals and \leavmg intervening sections 10 untreated.

If the sections 50 are more than twice the width measured along the illustrated in Fig. 7 is employed as the'weft, no particular relation of treated or untreated parts to the warp need be observed, since every section having a coating 50 will necessarily reach the back surface at some part of its run across the fabric and back. Treated sections 50 more than twice the width of the fabric may thus be scattered with a desired length of untreated space 10 between them, i and the whole wound for the weft, weaving with such a weft neces-' sarily'resulting in the generic structure illustrated in Fig. 1 It will be obvious without further descriptiontha'I an occasional coating when the treated yarn is in the position illustrated in Figs. 4, 5 and 6 vwill equally be effective. Fig. Sillustrates, for

instance, a structural'weft 4 having the bare spaces 10 andthe coatings 50,.

My invention is applicable not only to carpets and rugsto which it can be lapplied during manufacture, but may be applied to existing carpets and rugs, such as Oriental rugs or rugs in stock, unsalable because of their slippery qualities. As illustrated in Fig. 9, I have shown the backl surface of such an existing Oriental or other carpet or rug having a yarn 20 coated either throughout its length or in the manner illustrated in Fig. 7, attached to its surface by a sewing operation, hand or machine, for'instanee as illustrated in said iigure at a. The yarn 20 is sewn zigzag under any part of.the reticulation at the back of the rug, passing into the structural the structure of Fig. 1 or 99 f weft and the yarn which may be done by I body'at 21 and lying on the under surface As shown at b the be of a different slope shown at a,

between the points 21. zigzag stitches may from those and in some cases I l tached upon the may attach the yarn 20 as illustrated in Fig. 0 by a row of enchained stitches of an entirely separate sewing thread 24 which passes at the dotted runs 25 into the structural body of the carpet. As well understood by those skilled in ythe art, such a sewed structure as illustrated in Fig. lOvmay be made by a sewing machine having a penetrating needle, eye-pointed, a detaining looper 4for enchaining the thread carried by the needle, as at 26, and a thread-carrying looper for the thread 20 to distribute it as shown in said figure, whereby it' is atsurface of the article, thread 25 only penetrating any part of the body of the carpet or rug. Such stitching is familiar in gloves, underwear, and for overedging carpets and other cloths.

One .advantage of the structures illus-y trated 1n Figs. 9 and 10, which inures also to the structure illustrated in Fig. 4, is a slight increase of tension at the back or under surface of the fabric, which causes it to curl downward at the corners and thereby lie flat on the iioor without tendency to roll up at the corners.

What I claim is:

l. fabric adapted for a floor covering, including a textile or fibrous element having an adhesive surface and exposed at intervals on one face of the fabric.

2. A fabric for use as a covering for polished surfaces having incorporated therewith a yarn having a sticky covering adaptedto adhere to sa1d surface, the remainder of the fabric not being sticky.
